    • A Novel Method for Accelerating the Analysis of Nonlinear Behaviour of Power Grids using Normal Form Technique 
      Communication avec acte
      UGWUANYI, Nnaemeka Sunday; ccTHOMAS, Olivier; MARINESCU, Bogdan; ccKESTELYN, Xavier (IEEE, 2019)
      Today's power systems are strongly nonlinear and are becoming more complex with the large penetration of power-electronics interfaced generators. Conventional Linear Modal Analysis does not adequately study such a system ...
    • Confidence Level Optimization of DG Piecewise Affine Controllers in Distribution Grids 
      Article dans une revue avec comité de lecture
      BUIRE, Jerome; COLAS, Frédéric; DIEULOT, Jean-Yves; DE ALVARO, Leticia; GUILLAUD, Xavier (Institute of Electrical and Electronics Engineers, 2019)
      Distributed generators (DGs) reactive powers are controlled to mitigate voltage overshoots in distribution grids with stochastic power production and consumption. Classical DGs controllers may embed piecewise affine laws ...
    • Convex formulation of confidence level optimization of DG affine reactive power controllers in distribution grids 
      Article dans une revue avec comité de lecture
      BUIRE, Jérôme; DIEULOT, Jean-Yves; COLAS, Frédéric; GUILLAUD, Xavier; DE ALVARO, Léticia (Elsevier, 2020)
      Volatile productions and consumptions generate a stochastic behavior of distribution grids and make its supervision difficult to achieve. Usually, the Distributed Generators reactive powers are adjusted to perform decentralized ...
    • Laboratory Demonstration of a Multiterminal VSC-HVDC Power Grid 
      Article dans une revue avec comité de lecture
      AMAMRA, Sid-Ali; COLAS, Frédéric; GUILLAUD, Xavier; RAULT, Pierre; NGUEFEU, Samuel (Institute of Electrical and Electronics Engineers, 2017)
      This paper presents the design, development, con- trol and supervision of a hardware-based laboratory Multi- Terminal-Direct-Current (MTDC) test-bed. This work is a part of the TWENTIES (Transmission system operation with ...
    • Error Estimators for Proper Generalized Decomposition in Time-Dependent Electromagnetic Field Problems 
      Article dans une revue avec comité de lecture
      MULLER, F.; HENNERON, Thomas; HAMEYER, K.; ccCLENET, Stephane (Institute of Electrical and Electronics Engineers, 2020)
      Due to fine discretization in space and time, the simulation of transient electromagnetic phenomena results in a large system of equations. To cope with this computational effort, model order reduction techniques can be ...
    • Direct AC Voltage Control for Grid-Forming Inverters 
      Article dans une revue avec comité de lecture
      QORAI, Taoufik; LI, Chuanyue; OUE, Ko; COLAS, Frédéric; GUILLAUD, Xavier; ccGRUSON, Francois (2019)
      Grid-forming inverters usually use inner cascaded controllers to regulate output AC voltage and converter output current. However, at the power transmission system level where the power inverter bandwidth is limited, i.e., ...
    • Critical clearing time determination and enhancement of grid-forming converters embedding virtual impedance as current limitation algorithm 
      Article dans une revue avec comité de lecture
      QORIA, Taoufik; COLAS, Frédéric; DENIS, Guillaume; PREVOST, Thibault; GUILLAUD, Xavier; ccGRUSON, Francois (Institute of Electrical and Electronics Engineers, 2019)
      The present paper deals with the post-fault synchronization of a voltage source converter based on the droop control. In case of large disturbances on the grid, the current is limited via current limitation algorithms such ...
